Description

vegetable seeder

technical field

The invention belongs to the technical field of vegetable planting machinery, relates to a planter for planting vegetables in rural areas, and more specifically relates to a novel vegetable planter.

Background technique

In recent years, there have been reports of vegetable planters in China, but due to factors such as unreliable performance and limited sowing conditions, they have only been promoted in a small range. At present, when growing vegetables in rural areas, whether it is field planting or facility agricultural planting, manual and simple labor tools are still the main method, which is laborious, inefficient, and wastes seeds. Vegetable growers are very hard. There are three methods of artificial sowing: broadcast, drill and hole. The existing vegetable planting machines have the following defects: firstly, the density of sowing seeds is not uniform, and the seedlings are thinned out, and the seedlings need to be thinned out, which is very troublesome. Some shortcomings of sowing are overcome, but seedlings still need to be thinned, which also causes waste of seeds. Hole sowing is scientific, seed saving, good lighting and ventilation effects, uniform nutrition and reduced labor intensity of thinning, but low seeding efficiency. In addition, at present, vegetable planters are relatively large, and some have power, pollute the air during operation, the price of the whole machine is high, and it is inconvenient to move, so it is difficult to apply in vegetable planting in facility agriculture. For example, South Korea’s Bolante JP series seeder, as shown in Figure A, its structure includes frame a, two front and rear compaction shafts b, seed box c, push handle d, transmission chain e, ditch opener f, Coverer g, etc.; Figure B is the design of the seed box of the South Korean planter, including the seed box h, the seed brush i, the seeding wheel drive gear j, the seeding wheel k, and the seeding hole m. Judging from the problems reflected by the actual sowing of vegetable farmers, this vegetable seeder has four main defects: (1), the seeder is too heavy, and the design of the front leveling shaft makes the frame too long. (2) As long as the planter is pushed, the planter will start to sow, which will cause waste of seeds when changing rows or changing sheds, or it will be troublesome when unloading; ( 3) The seed box of the seeding device and the seeding device are integrated and it is not easy to disassemble and change seeds; (4) The seeding wheel is easy to crush the seeds and block the seed hole during the rotation of the seeding wheel, and the seeding wheel cannot be used for normal seeding. Resulting in a lack of monopoly rows in vegetable beds.
